Abstract

This document is applicable to the borehole shear test using the phicometer procedure, commonly named the phicometer test. The test can be performed in all types of natural soils, fills and artificial soils, which can be saturated or not. It does not apply to very soft fine soils, very loose coarse soils, medium strong to very strong rocks and natural or artificial soils with a predominance of cobbles having a particle diameter greater than 150 mm. The test can also be carried out in soils presenting a resistance outside these application limits as long as the representativeness of the results is assessed or validated by the analysis of the PBST graphs (see Clause 8). This document applies only to tests carried out at a depth less than or equal to 30 m. The parameters derived from this test are the shear strength properties, as the cohesion and angle of friction.
